摘要:
A feed through for an active implantable medical device (AIMD). The feed through comprises first and second substantially planar, electrically non-conductive and fluid impermeable substrates usable for semiconductor device fabrication, each comprising: an aperture there through, and a contiguous metalized layer on the substrate surface that is co-existent with a section of the perimeter of the aperture and extends from the aperture; and a bond layer affixing the metalized layers of the first and second substrates to one another such that the apertures are not aligned with one another, and such that the metalized regions form a conductive pathway between the apertures.

摘要:
A cochlear implant electrode assembly device (10) comprising an elongate electrode carrier member (11), a first stiffening element (15a), and a second stiffening element (15b). The carrier member (11) is made of a resiliently flexible first material and has a plurality of electrodes (12) mounted thereon. The carrier member (11) has a first configuration selected to allow it to be inserted into an implantee's cochlea (30), a second configuration wherein it is curved in shape to match a surface of the cochlea (30), and at least one intermediate configuration between the first and second configurations. Both the first and second stiffening elements (15a, 15b) are made of a material relatively stiffer than said the material and in combination bias the elongate member into the first configuration. If either the first stiffening element (15a) or the second stiffening element (15b) are removed, the elongate member (11) adopts the at least one intermediate configuration.

An electrode array for a cochlear implant is formed with a carrier made, for example from silicone, is preshaped and is formed with a lumen. The array is shaped to assume a first. The array can be straightened, and held in a straight configuration by inserting a stylet into the lumen. The array relaxes to a shape matching the curvature of the cochlea when the lumen is removed. The electrodes of the array are disposed on one side of the array to face the modiolus when the array is inserted into the cochlea.
